Some of the stuff in this video , just wow! I can see @andy_con doing this sort of stuff, after a lottery win maybe?

They are pretty amazing and yes I'd love to give something like that ago.

Struggling with solidworks cam to emco mill as unsure on the post processor to use and can't find anything online!

Anyone have any ideas? Takes the piss manually programming it. If anyone needs anything doing on solidworks let me know too.

Haha, I don't mind using gcode but would rather it be straight off slw

Me too, and not all little shitty things either!

The planning for that just said 'bore'! It was planned for 70 hours machining and took over 200. Nice change from shitty cast iron or w**k fabrications we do.

Currently on the way down to haas to look at a few 5 axis machines! Should be a good day out

saw one of the haas 5 axis machines last year in person at a trade show, amazing bits of kit. shame its to big for my workshop.

any bigger and id need planning permission

make sure you get a video of it in action

Unfortunately not allowed phones! It was the haas f1 factory amazing place! kevin magnussen’s car was in! There 5 axis was amazing! Time to convince work to invest lol

@OssPoop @andy_con

if i wanted something cnc'd what file format would a file have to be, the drawing ive got at the moment is .STL

Are you thinking of sending a cad model? Probably better off making a 2d manufacturing drawing if you can.

 

[PhillipM]

Better with either a solid model or as above, 2d dimensioned drawing. an STL is just a hollow surface shell so can be tricky to work off if it's not perfect.

Depends what you want machining

 

[Louis]

We always do Engineering DWG'S and if the part is really complicated we just include some .step files.

 

[Clio_fool]

If a machine shop can't figure it out from a 2d drawing I wouldn't trust them with they job! I've had some really s**t and complicated multi page drawings to work from but always figured it out. Never thought a 3d model was necessary to get the job done.

 

[Matt e]

would a .SLDPRT file be better?

 

[Louis]

I can mock you a drawing up if you want, aslong as it's not commercial

 

[Steven103]

Plenty of frustrating things from the other side of the fence. My two favourites will always be:

People who insist on having 2D in a PDF, only to spend their own time (and expect to amortise it into piece price) creating a dwg/dxf. Where do you think the PDF came from?!?! (if there was ever a time for the confused Jackie Chan meme...).

People who insist on doing stuff from 2D, but then ignore the stated tolerances.

 

[Clio_fool]

80% of the machining work we sub con comes back wrong. I can't understand how people cam be so s**t at their jobs.

 

[botfch]

Do you use G code out of interest?

 

[Clio_fool]

Do you use G code out of interest?

I program on the machine in heidenhain conversational. Would have to rack my brain for the g and m codes now?

 

[M.C..]

Does anyone use Hypermill?
We got it at work a while ago, only tried to use it today and find it really complicated I have done a 3 day course but it still don’t make much sense lol.

No, but I wish I did ?

[Clio_fool]

When you enter a 7 instead of a 9 and the cutter isn't quite clear of the job.

Not a bad effort for 15m/min. Didn't even break the inserts?.

 

[PhillipM]

New surface finish option there, gotta be another 50 quid for decorative edge reliefs

 

[Andy_con]

one thing I don't have and would love is a lathe.

anyone able to do me maybe 10-15 ally parts on a lathe? all the same and pretty simple nothing complex. also not very big, maybe 70-100mm dia

How accurate? I have a little lathe that should do something about 100mm failing that I do have access to a big one but that’s not as guaranteed but it will be far more accurate.

not mega accurate, its only a ally cap to cover a plastic cap under the bonnet of a car.

internal dia needs to be roughly accurate so it fits over nicely, but outside doesn't matter

Could quite easily do them depends if you want any fancy rounded edges or anything.

If they’re just straight alu cups then it shouldn’t be too difficult

id like some form of none sharp edge, so either rounded or 45

 

[Jaff.]

45 can be done. Rounded edge would require a tool to be bought lol

 

[Andy_con]

ok well let me get to it on my todo list and we can do a test part see how it comes out

 

[Louis]

I can also help out if needs be.

Having a day out at mazak tomorrow to look at some fancy machinery!
